How we interpret a situation is dependent on our worldview. Hermeneutics is divided into two types - superficial and in-depth interpretation. Souls are valuable to God and so should they be to us. The harvest is plenty but God is need of people that can interpret the message correctly, in-depth interpretation. God is asking where are his people who can reach out to the lost souls. God is looking for people that are filled with his word, full of light, to go evangelise diligently until the lost are saved. When a soul comes home the death of Jesus is justified. The value of souls is invariable , it is permanent, it was set before it all. However usefulness is variable on who is in control of your life, who owns you. All souls are valuable but only those in Gods hand are useful.
